NMG_KILL_V(nged)

💖 NMG_KILL_V(nged) — your vertex-removal bestie 💖

okay bestie, this is NMG_KILL_V from the nged manual — the header’s manual crew is BRL-CAD User Commands — and it’s literally all about removing a vertex from an NMG solid by coordinates. lowkey surgical, highkey iconic 💅✨

🌸 NAME 🌸

nmg_kill_v - remove a vertex from an NMG solid by coordinates 🎀

✨ SYNOPSIS ✨

nmg_kill_v nmg_name V x y z

🦋 DESCRIPTION 🦋

Okay so this command (nmg_kill_v) removes the vertex at model-space coordinates (x, y, z) from the NMG solid nmg_name. That’s the whole main-character move: you point at the solid, you point at the coordinates, and the vertex gets yeeted 🫶.

The literal token V must appear as the second argument. Like, literally V — no substituting, no improvising, bestie.

The vertex is located by matching its stored coordinates to the provided values. So it’s a coordinate match-up situation, iykyk 👀.

Removing a vertex also removes its vertexuse, its vertex geometry, and all higher-order topological elements (edges, loops, faces) that depend on it. Not me warning you that this is a whole dependency situation 😭 — it’s giving “remove one thing, clean up the whole friend group.”

Use labelvert nmg_name to display the model-space coordinates of all vertices in the solid before running this command. That’s your pre-game vibe check: peek at the coordinates first, then go remove the right one 💖.

The nmg_kill_v command is the standalone form of the nmg <object> kill V subcommand.

🎀 EXAMPLES 🎀

Example 1. Remove a vertex at known coordinates

mged> labelvert my_nmg.s mged> nmg_kill_v my_nmg.s V 50 100 0

First displays all vertex coordinates in my_nmg.s, then removes the vertex at (50, 100, 0).
